Saenai Heroine no Sodate-kata

The life of Tomoya Aki, a highschool otaku working part time to support his BD hoarding. With remarkable luck, he bumps head-first into, Megumi Kato, the most beautiful girl he has ever seen. Naturally, the meeting twists his life into a complicated torrent of relationships. Eriri Spencer Sawamura, his half-foreigner childhood friend who's always valued her relationship with MC. Kasumigaoka Utaha, a cold, composed renowned literary genius who shoves everyone aside from our protagonist. What is this? An eroge introduction? The tale of a small not quite doujin circle, but not quite indie studio's journey through the tough territory of comiket and beyond.

A slightly adjusted retelling of Saenai Kanojo no Sodatekata but with a heavier focus on Eriri Spencer Sawamura as the main heroine.

Individual stories with each of the *Saekano* heroines!? Which girl do you want to XX with? A fanfic volume packed with special scenarios, like a Ferris wheel ride for two, an intimate conversation in a private room, conducting otaku training (?) of a non-otaku girl, and many more sweet (and maybe more) stories with all of the beautiful girls!
